PRECIS DE LA DIVULGATION:
L'invention concerne une méthode d'activation de per-
composés, caractérisée en ce que l'on ajoute au percomposé un
activateur choisi dans le groupe constitué par le tris (acétoxy-
méthyl) phosphine-oxyde (I):
(CH3 ? O CH2)3 P O (I)
et deux de ses précurseurs: la tris (acétoxyméthyl) phosphine (II)
et les sels de tétrakis (acétoxyméthyl) phosphonium (III):
(CH3 ? O CH2)3 P (CH3 ? O CH2)4 P?, X?
(II) (III)
où X? désigne un anion minéral ou organique, ou par des mélanges
de deux ou plusieurs des composés (I), (II) et (III) entre eux.
Les activateurs de l'invention sont utilisés dans tous les cas où
un percomposé est mis en oeuvre pour obtenir une action oxydante
ou de blanchiment, par exemple dans le blanchiment des fibres
textiles, des huiles, graisses et cires, les traitements des
cheveux et de la peau en cosmétologie, la passivation des surfaces
métalliques, les techniques de purification, de désinfection et
de stérilisation. Ajoutés au percomposé ces activateurs permet-
tent d'obtenir une action de blanchiment ou d'oxydation plus rapide
à température donnée; ils permettent également d'obtenir un même
effet de blanchiment en travaillant à température plus basse.
